Title: Manufacture of thermoplastic foams
IPC: C08J9/00
Filed: 1966-03-02
Abstract: 1,138,473. Thermoplastic foams. SOC. NATIONALE DES PETROLES D'AQUITAINE. 2 March, 1966 [3 March, 1965], No. 9207/66. Headings C3C, C3P and C3R. Foamed thermoplastic material is obtained by introducing under pressure an expansion fluid into a molten polymer in which are dispersed porous particles of an inorganic material which is neutral with respect to the polymer. Suitable thermoplastics are acrylic, vinylic and aromatic vinylic polymers and polymers of acrylonitrile derivatives, e.g. acrylate and methacrylate polymers and polymers of vinylic, acrylic and methacrylic halides and esters; polyamides; and especially polystyrene or copolymers of styrene. The porous powder may be alumina, silica, activated carbon, absorbent clays, metallic oxides, silicates, carbonates &c., e.g. fuller's earth, diatomaceous earths, magnesias, iron oxides, pumice, thorium oxides, bauxite, bentonite and molecular screens. The expansion fluid may be a gas, e.g. carbon dioxide, nitrogen, methane, methyl chloride or bromide, ethyl fluoride, difluorodichloromethane or a volatile liquid, e.g. paraffinic and olefinic hydrocarbons such as pentane, hexane and heptane, ketones such as acetone and methylethyl ketone, alcohols especially methanes, ethanes and propanes, ethers and esters with a heating point below 160‹ C. in water. The process may be carried out by melting the polymer in the presence of the porous powder in an autoclave and then injecting the expansion fluid or if the latter is a liquid it may be introduced before heating the polymer. A preferred method consists in supplying a combined mixing and extruding machine with the polymer, porous powder and expansion fluid.

Title: Improvements relating to electric switchgear
Inventor: CHRISTIE JOHN
IPC: H02B11/20
Filed: 1954-04-05
Abstract: 768,693. Switchgear structures. REYROLLE & CO., Ltd., A. July 1, 1955 [April 5, 1954], No. 9976/54. Class 38(5) In electric switchgear having a junction chamber 23 interconnecting two switchgear components 15, 27 and enclosing a bolted connection 31 between insulated conductors connected to the components, the chamber is formed of moulded synthetic resin and has the conductor 19 embedded in one wall and an aperture 25 in another wall through which the other conductor and its associated separate insulation extend, the latter conductor and its insulation being withdrawable when the bolted connection 31 is dismantled. In the arrangement of Fig. 1 a vertically withdrawable "dead-tank" circuit-breaker 10 has terminal bushings 12, 13 co-operating with orifice bushings of a bus bar unit 14 and a current transformer 15 having its high voltage windings embedded in a moulded block of synthetic resin as described in Specification 743,002, [Group XXXV]. In this case the chamber 23 is moulded integrally with and forms a lateral extension of the current transformer block which is also formed with an orifice bushing 22 for the connection of a voltage transformer 21. The chamber 23 interconnects the current transformer with a cable chamber 27. This arrangement may be modified to permit horizontal withdrawal of the circuitbreaker. In alternative arrangements the conductor 42, Fig. 3, extending from the cable chamber 27 may be embedded in the base of the chamber which is not integrally moulded with the current transformer 44, the bushed conductor 47 extending, from the current transformer through an aperture in a side wall 45 of the chamber. In this case the L-shaped bolted connection 43 has a contact post 52 which may be engaged by a test bushing 55, Fig. 3, or an adapter connected to a voltage transformer Fig. 2 (not shown) extending through an aperture in cover 48 of the junction chamber. In other arrangements a voltage transformer terminal bushing may extend through an aperture in the cover Fig. 4 (not shown) or through another side wall of the chamber, Fig. 5 (not shown). In a three phase arrangement a single chamber could have three bolted connections and the chamber may be oil-filled and have its external surfaces covered with an earthed metal skin e.g. formed by metal spraying.

Title: Shiftable change speed gear
IPC: F16H3/08
Filed: 1975-03-11
Abstract: 1479846 Change-speed gears; positive clutches EATON CORP 11 March 1975 [20 March 1974] 9996/75 Headings F2D and F2C For selectively connecting a gear-wheel 72 to a shaft 23 a jaw clutch comprises an externally toothed member 42 connected to the shaft by splines 43, 44 and resiliently urged by a spring 47 towards a stop 46, and a blocker ring 81 with a conical friction surface 56 engageable with a conical bore 57 in the member 72 and having means, e.g. a spring ring 55 housed in an annular groove 54, frictionally gripping the teeth 48 of the member 42 in a manner to provide appreciable axial drag but negligible rotational drag between the ring 81 and member 42. When the wheel 72, which is in constant mesh with a countershaft wheel (not shown), is displaced leftwardly to engage the clutch it displaces the blocker ring and member 42 against the spring 47 until, on synchronization, clutch engagement is effected by return movement of the member 42 under spring pressure to engage the teeth 48 with internal teeth 50 of the wheel 72. The axial drag of the ring 55 on the member 42 ensures that the conical surfaces 56, 57 are pressed together so that the blocker ring turns partially on the member 42 to prevent clutch engagement before the shaft and wheel are synchronized. Three equally spaced teeth of the member 42 are partially removed so that remaining portions 49, 49A, 49B coact with pairs of internal projections 82, 83, 82A, 83A and 82B, 83B on the blocker ring, these projections being of lesser width than the spaces between the teeth 48, as shown in Fig. 5, to permit limited rotation of the blocker ring between positions indicated in Fig. 7 by cross-hatching and dashed outlines. The tooth portions 49 are enabled to pass between the projections 82, 83 at synchronization. To permit clutch engagement at rest the ends of the projections 82, 83 are inclined as shown in Fig. 7 at an angle sufficient to produce relative rotation between the blocker ring and member 42. The Specification describes the application of jaw clutches as described above to a transmission as disclosed in Specification 1,446,598 comprising a main section providing four forward ratios and reverse, and a series-connected range section providing two ratios, a main shaft in each section flanked by a pair of countershafts, and shift mechanism for the main section interconnected with fluid-operated shift mechanism for the range section.
